My favorite mouse was a mini traveler Genius mouse which I have been using for 6 years. It was perfect. It only recently started to have problems with the left click button so I decided to get a new one. This one is exactly the same except for the size, it is bigger. I love it. It is well built, precise, it clicks nice and works on almost any surface despite the cheap price. I would highly recommend it.
Having received one of these mice as a freebie I decided to purchase another two. These have a pleasent feel to the buttons, excellent control and the red diode light filters through, around the buttons, giving it a some what techy feel that might just give it that little extra appeal.
Just about every mouse works fine. This one is special because it has a very nice feel in the hand, both to hold and also to click.
The plastic is textured, which makes it easy to hold and shift about - it feels secure, and not slippery. The mouse buttons are quiet and have a nice, refined positive sensation to the press. Much nicer than other mice I've used so far.
The scroll wheel is nice to scroll. Grips nicely to the finger. I've experienced some mice where the scroll wheel is slippery and you have to press harder to get a grip. But not this one.
Most mice are okay. They do the job without fuss. This one does the job and feels nice to use as well.
Another Genius product I've experienced that's cheap and very cheerful!
